COOKING-STOVE.

Specification of Letters Patent.

Patented June 4, 1907.

Application filed August 29,1905- Serial N0- 276,218.

To all whom it may concern:

Be it known that I, VIoToR M. BRASCHI, a citizen of the United States of America, and a resident of the city of Mexico, Mexico, have invented certain new and useful Improvements in Cooking-Stoves, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in cooking stoves, and particularly stoves for the purpose of baking articles by the direct heat from a furnace a ainst the under side of a thin plate supporting them. The stove is particularly designed for cooking tortillas or griddle cakes in this manner.

A stove constructed in accordance With my invention comprises a rotatable tray carrier, a plurality of trays arranged to be supported and carried thereby, and a furnace, from which direct heat is applied to the under side of the trays supported by the carrier. The tray carrier is arranged to support the trays at an angle to the horizontal, and the products of combustion fronr the furnace are arranged, after impinging upon the under side of the trays, to pass up through a central flue, as will presently be explained in greater detail. The tray carrier is revolved intermittently, whereby a certain time is allowed for baking the article supported by some of the trays, the time being utilized for removing and replacing other trays, and for turning the cakes over on still other trays.

My invention also consists in certain details of construction and arrangement of parts, and in a novel form and construction of the furnace portion of the stove, all as will hereinafter more fully appear.

In order that my invention may be fully understood, I will describe in detail, and with reference to the accom anying drawings illustrating same, a coo ing stove embodying my invention, and will then point out the novel features in claims.

In the drawingsFigure 1 is a view in central vertical section of a cooking stove embodying my invention; Fig. 2 is a partial top view and a view partially in horizontal section of the same; Fig. 3 is a detail view of a portion of the driving gear; Fig. 4 is a view in central vertical section taken at right angles to the plane of section of Fig. 1; and Fig. 5 is a view in vertical section taken substantially upon the plane of the line 55 of Fig. 1. Fig. 6 is a top view of the stove with the tray carrier removed.

The furnace portion of the stove herein comprises two oppositely arranged combustion chambers 10 10 and intermediate cool spaces 33 33. The outer'walls 11 of combustion chambers blend into and are united by a circular wall 12, and the inner walls are connected by an arch 13. Flues 14 rise up from the combustion chambers 10, and discharge into a central flue 15. Baffles 16 may also be employed toproperly direct the products of combustion, if desired.

A carrier 17 is arranged above the furnace portion, being supported upon a shaft 18 mounted concentrically of the stove and driven by suitable gearing. The lower end of the shaft is journaled in a foot bearing 19, and the upper end of the shaft is suitably guided by a bearing 20 in the arch 13. The carrier 17 is preferably of conical form, and comprises a spider 21 directly supported by the shaft 18 at its upper end, and a skeleton framework composed of an upper ring 22, a lower ring 23, connecting bars 2 1, and spacing pieces 25. A conical open-top hood 26 constitutes the walls of the flue 15, above described and is mounted on the carrier 17 to rotate with it. A stationary hood 27 may conveniently be arranged above the fine 15,

said hood being connected with the chimney stack to convey away the products of com bustion, as will be well understood.

The driving gear for the shaft 18 comprises a bevel gear 28 upon the shaft 18, in mesh with a bevel gear 29 upon a horizontal shaft 30. This horizontal drive shaft carries a spur gear 31, with which a mutilated pinion 32 engages. The relation of the pinion 32 and spur gear 31 toeach other is such that continuous rotation of the pinion 32 imparts intermittent movement to the spur gear 31, the carrier being caused to revolve at uniform speed for one quarter of a turn, and then to remain stationary for a certain period.

The carrier is designed to support a suitspaces 33 and free to be handled. At one of these places, then, the trays may be removed, after the cooking is completed, and may be replaced by other trays carrying fresh material to be cooked, while at the opposite side the articles may be conveniently inverted, so that, having cooked on one side while over one ofthe combustion chambers 10, they may be cooked upon the other side when over the other combustion chamber 10.

It will be noted that the flues are so arranged that all the products of combustion will passfrom the flues 14 into the central flue 15 and thence to the hood 27. Thus there will be no waste of heat, nor will the attendant be exposed to the direct heat of the combustion chambers when removing the trays, as would otherwise be the case. By making the carrier 17 generally of a conical form the attendant will be enabled to re move the trays therefrom much more easily than he could if they were supported horizontally, for it is obvious the upper end of the tray willbe nearer to the attendant when supported on an incline as shown than it would be if supported horizontally.

What I claim is:

1. In a cooking stove, a furnace portion comprising oppositely arranged combustion chambers and intermediate cool spaces, combined with a rotatable carrier supported above said combustion chambers and cool spaces, said carrier comprising a skeleton frame and a plurality of trays removably supported on the skeleton frame and adapted to carry the articles to be cooked.

2. In acooking stove, a furnace portion comprising oppositely arranged combustion chambers and intermediate cool s aces, combined with a carrier supporte to rotate above the combustion chambers and cool spaces, said carrier com rising a skeleton frame and a plurality o trays removably supported on said frame and adapted to carry the articles to be cooked, and a gearing for imparting intermittent rotary movement to the said carrier.

3. In a cooking stove, a furnace portion comprising two combustion chambers and intermediate cool spaces, combined with a carrier supported to rotate above the com bustion chambers and cool spaces, said carrier comprising a skeleton framev and a plurality of trays removably supported on the frame, said trays being exposed to the direct heat from the combustion chambers and adapted to carry the articles to be cooked.

4. In a cooking stove, a furnace portion comprising a plurality of combustion chambers and intermediate cool spaces, combined with a carrier supported to rotate above said combustion chambers and cool spaces, said carrier comprising a skeleton frame and a plurality of trays removably supported thereon and adapted to carry the articles to be cooked, and a flue supported upon said carrier to rotate therewith and with which all of said combustion chambers communicate.

5. I11 a cooking stove, a furnace portion comprising a plurality of combustion chambers and intermediate cool spaces, combined with a carrier supported to rotate above said combustion chambers and cool spaces, said carrier comprising a skeleton frame generally of conical form, and a plurality of trays re movably supported on said frame.

6. In a cooking stove, a furnace portion comprising a plurality of combustion chambers and intermediate cool spaces, combined with a carrier supported to rotate above said combustion chambers and cool spaces, said carrier comprising a skeleton frame and a plurality of trays removably supported thereon, said trays being exposed to the direct heat from the combustion chambers, a flue supported by said carrier to rotate therewith and having communication with all of said combustion chambers, and a hood supported above the flue for carrying away the products of combustion.

7. In a stove, the combination with a vertical shaft and a substantially conical carrier frame supported thereby, two combustion chambers arranged one on each side of the said shaft beneath the carrier frame, cool spaces intermediate the combustion chambers, a central flue supported and carried by the said carrier, arranged in open communication with the combustion chambers, removable trays supported by the framework, gearing for lntermittently rotating the carrier framework, and a hood for carrying away the products of combustion, arranged above the central flue.

8. In a stove, the combination with a ver tical shaft and two combustion chambers arranged one upon either side of the said shaft, a carrier framework carried by the shaft, having tray supporting portions arranged at an angle to the horizontal, whereby the trays will be supported at an angle above the combustion chambers, a central flue carried by the said carrier, said combustion chambers communicating with the said flue, but occupying a portion only of the space around the shaft, whereby intermediate cool spaces are left between the combustion chambers, gearing for imparting intermittent rotary movement to the said shaft, and for holding the same in a rest position for periods intermediate the periods of movement, and a plurality of removable trays for the said carrier, substantially as set forth. i
